Pathogenesis of multi-organic failure in autoimmune diseases

Area of Science:

• Immunology
• Pathophysiology
• Systems Biology

Background:

• Autoimmune diseases can lead to multi-organ failure via complex, multifactorial pathways.
• Normal physiological cascades (coagulation, fibrinolysis, kinin, complement) become pathologically dysregulated.
• Immune system activation, particularly endothelium activation, is a common response pattern.

Purpose of the Study:

• To review commonalities among major plasma cascades and their activation mechanisms in disease.
• To elucidate how these pathways contribute to a global clinical picture of multi-organ dysfunction.
• To present Macrophage Activation Syndrome and TGN1412-induced cytokine storms as examples of shared underlying pathology.

Main Methods:

• Literature review of plasma cascades and immune system activation pathways.
• Analysis of common points and feedback loops in pathological conditions.
• Comparative study of two distinct clinical settings with shared mechanisms.

Main Results:

• Identified shared activation points and positive feedback loops in coagulation, fibrinolysis, kinin, and complement cascades.
• Highlighted standardized endothelial cell responses involving p38, JNK, NF-κβ, and IRF-3 pathways.
• Demonstrated that Macrophage Activation Syndrome and TGN1412-induced cytokine storms share common pathophysiological underpinnings.

Conclusions:

• Dysregulation of plasma cascades and immune activation are central to multi-organ failure in autoimmune diseases.
• Understanding these shared pathways offers insights into distinct clinical manifestations.
• This knowledge may inform therapeutic strategies for conditions involving systemic immune dysregulation.
